CARPET CLEANER. z i

Application led January 20, 1921. Serial No. 438,644.

To au, whom t may concern.'

Be it known that I, DAVID FIRnsToNE, a citizen of the United States, residing at Hancock, in the county of Houghton and State of Michigan. have invented certain new and useful Improvements in Carpet Cleaners, of which the following is a specifica-tion.

My invention relates to improvements in carpet, rug, Iand the like, cleaners, by means of which the article to be cleaned is carried through the various stages of beating, dusting, washing,l and steaming, etc., whereby any dust or dirt is removed therefrom with speed Aand eiiiciency. By means of the device the article may be easily introduced into or removed from the same with the minimum amount of labor.

vThe object of the device is to so construct the same, that not only will an efficient machine be the result, but it will have few parts, will be cheap, durable, easily constructed and operated, yand the parts comprising the same be renewed or supplied with the least possible trouble In the drawings'forming a part of this specification, and in which symbols of reference represent corresponding parts in `the several views Figure 1 is a side elevation of the device, the dotted lines indicating the covering for the rear of the machine, roll 3 being above shaft 40 and tothe right of the same;

Figure 2 is a side elevation opposite to that shown in Figure 1;

Figure 3 is a front view, with gear32 on shaft 31 and its associated parts left out for clearness, the same being shown in Figure 4.

Figure 4 a rear view, partly in sect-ion, the `dotted line indicating the coveringfor the device; f s

Figure 5 is a sectional view,. showing shafts and lever for operating same, `to throw the brushes into orl out of operation.

Figure 6 is la side'view, showing the Vconstruction of the beaters; x

In the drawings, 1` represents the pulley connected to the main `drive-shaft 40; 2 a transmission `pulley connected to the driveshaft by a belt41; 3, 4, 5 and 6 are the carrier rolls over which operatebelts 24 to convey the carpet or'other article to be cleaned; and 7 is the dust brush. The dust brushis operated by a band 27 passingover pulleys 42, supported by'frame 43; and connected to thedrive-shaft 40. 8 is the. scrubbing brush, which is operated by a band 28 passing over pulleys 44, supported by frame 45; and 9 is a vessel for the cleansing liquid.

10 is a clutch for control of the beaters, the same adapted to be operated by lever 10a, which is journaled `at 46 in the main frame; and 31 is a link connecting the lever with clutch for operating the same. 47 and 48 are shafts journaled at-.49 in the frame of the machine Vand having connected to the same worms 11, adapted to be engaged by gears 11B. 52 is a lever having teeth engaging a segmental rack 50, by means of which the brushes may be operated to throw them into or out of operation. f51 are' springs on the rods for the purpose of keeping the belts tight while that sideof the machine is in operation.

When the dry cleaning brush isvto be brought into use the lever 52 is turned toward the brush to be operatedythus'tightening the belts onthat side; and is turned in the opposite direction to control the washing brush. '.VVhen the lever is at neutral,

or vertical, neither brush is running. 53

are rods supporting the brushes and being supported from the main frame -by vlinks 54, pivot-ed-at 55 to rods 53, so asto give them a swinging'movement.

14 are threaded rods for raising and lowering the vessel 9` the same being journaled in the frame at 56 and in the side of the vessel at 57. I rIhey are provided with gears 58 which engage pinions 59 on a shaft 60, and said shaft is operated by a crank 61, and the vessel adjusted as desired. 12 are threaded rods having at theirbase gears 62 adapted to engage wheels `68. on the ends of rod 64, which is journaled in the kmain .frame and adapted 'to be operated by crank 123-by means of which the rods 12 may be operated inthe supports 65 and 66, supsion ofthe carrier belts be adjusted,

13. is a beltr to be connected to the source o'f.poweras an engine or motor. fixed pulley connected to roller 68,` from which thevarticle tobe cleaned is fed into or removed from `the cleaner. 16 is a loose pulley on the above-described roller; 21 a portedat-67 tothe frame, and thus the ten- 15 is a r11 foot lever for shifting the belt 'on pulleys 15 and 16 through'the medium of ashaft ,69 carrying fingers 70 Vembracing said belt.

17 is a camv shaft for operatingthe beat ers, the same carrying cams 22.' 71 is a shaft yupon which kare journaled. a series of blocks 72 by staples 7 3; and said blocks have cut-away portions 74 Within which op- ,essere frame, a series of carrier rolls journaled in the-same, belts on` said rolls for carrying the erate base pieces 7 5, also journaled on. shaft article to be cleaned, a drive-shaft, a series 71. Connected to pieces 7 are the beaters 18, which have elongated staples 76 embracing them, the purpose of the same' being to control the play of the beaters. Staples 73 are fast in blocks 72: 74 are springs on blocks 72, the same being connected to shaft 71 and extending down to the base of the blocks, the beaters 18 passing beneath the same and being normally held'against a rod 78', so that they are firmly held until open ated upon by the cams. Rod 78` is journ'aled iiil the frame at the sides' of the same in the links' 79.' The beaters 18 not only have a vertical movement and strike the article on the surfaceV when the cams' contact with' pieces 75', but also a horizontal movement throi'igh the" medium of shaft' 25 carrying A Wheel81 which engages gear 82 connectedvwith the camI shaft, the other end of shaftQ/' carrying a' cam 83. Shaft 25 is jourrnaile'd i-n frame 84:,I supported from the mainframe. When eamdv is rotated iteontacts With'eolla'rs 85* and 86 on shaft 71', and said shaft is reeiprocated and with it the beaters; 87 are collars on shaft 71 to hold the blocks 72 fin proper' relation.

1:9 is the blovverto create a vacuumv and remove the dust as it is beaten from the article.- 2O is a'r'aelr from which' the article to be cleaned is fed into'or removed from the machine; 88 are collars 'on' shafts 47 and 418 thepurpose of the'fsaim'e being to prevent the brush going too' hard againstv the carpet.: 23`is a perforated pipe from which steam may be applied to the article to be cleaned, the source of supply being connected to the end of the same. The perforated pipe lforms apart of shaft 60,l being `iournaled in the frame of the machine, as shown in Figure 1.

89 is" a shaft up'oir which the blocks 72- a're Jiournalc'd by staples 9() located on the back of said blocks; and said shaft 89 is supported in links 79'at the sides of the' machine.

The operation of the machine will be apparent* from the foregoing description. The article to be cleaned is fed from the rack onto the carrying belts which feed them intoT the machine as the feed rollers are operated, ivhen it isvr dusted, beaten, Washed and ify desired, steam appliedto it. The refuse is carriedr from' the machine nby the blo'iver or fan creating a suction. The cam shafts not' only givey the beaters vertical play, butv they are operatedl horizontally by the cam. Thus the entire surface of the carpetv is reached.

u Having n'ovvA fully describedv my invention", what I' claim as new, and desire to secure by Letters Patent, is

1L' lin'Y a ca-rl'net cleaning machine, a main of beaters, ashaft upon which the beaters are journaled, a cam shaft journaled in the frame, earns carried by the shaft and adaped to impart vertical movement to the beaters, and a cam having connection with the cam shaft and adapted to impart a reciproeating movement to the beaters.
